Guinean magistrates indicted the former head of the ousted junta on Wednesday in Burkina Faso over the 2009 Conakry stadium massacre in which at least 157 protesters were killed, his lawyer said.

"He has been indicted by a pool of magistrates visiting from Conakry to question him about his involvement in the events of 28 September 2009," Captain Moussa Dadis Camara's advocate Jean-Baptiste Jocamey Haba told AFP by phone from Burkina Faso's capital Ouagadougou, where Camara lives.

A spokesman for Camara's political party said the soldier, who has been in exile in Ouagadougou since 2010, would for the first time give evidence as "the accused and not simply as a witness".
